type Impression struct {
   Id  int `orm:"column(id);auto" description:"id"`
   ID  string `orm:"column(i_d)" description:"i_d"`
   URI string
   Ad  *Advertising `orm:"rel(fk);index;null"`
}

插入数据的时候

requestData := utils.JsonToMap(string(this.Ctx.Input.RequestBody))
o := orm.NewOrm()
var adObj models.Advertising
err := o.QueryTable("advertising").Filter("id", requestData["Ad"]).One(&adObj)
impressObj := models.Impression{ID:requestData["ID"].(string), URI:requestData["URI"].(string), Ad: &adObj}
//impressObj := models.Impression{}
//err := this.ParseForm(&impressObj)
fmt.Println("current data", impressObj)
if err != nil {
   logs.Error(err)
   this.Ctx.ResponseWriter.WriteHeader(400)
   this.Data["json"] = map[string]interface{}{"msg": "数据获取失败"}
   this.ServeJSON()
   return
}
_, err = orm.NewOrm().Insert(&impressObj)
if err != nil {
   logs.Error(err)
   this.Ctx.ResponseWriter.WriteHeader(400)
   this.Data["json"] = map[string]interface{}{"msg": "创建失败"}
   this.ServeJSON()
   return
}
this.Data["json"] = map[string]interface{}{"msg": "创建成功"}
this.ServeJSON()
return

orm.debug=true

插入数据的时候打印的mysql数据是

INSERT INTO `impression` (`i_d`, `i_d`, `u_r_i`, `ad_id`) VALUES (?, ?, ?, ?)

请问这是为什么呢？
